Rosetta Genomics Selected by a Global Pharmaceutical Company to Supply FISH Testing Services for Clinical Study in Prostate Cancer

Chosen from among numerous larger labs based on quality and
reliability

PHILADELPHIA & REHOVOT, Israel--(BUSINESS WIRE)--Rosetta Genomics Ltd. (NASDAQ:ROSG), a leading developer and provider of
microRNA-based and other molecular diagnostics, today announces that the
Company has entered into a services agreement with an unnamed global
pharmaceutical company to provide Fluorescence in Situ Hybridization
(FISH) testing services for a clinical study the pharmaceutical company
is conducting in prostate cancer.

The study will use FISH to determine the phosphatase and tensin homolog
(PTEN) gene status of a number of prostate adenocarcinoma cases. The
concordance of the FISH results will be assessed for cases where PTEN
status was previously established by immunohistochemistry (IHC). The
primary goal of the study is to determine if PTEN by FISH detects
cancers that IHC did not.

“We are very pleased to have our FISH testing selected by this global
pharmaceutical for their clinical testing study. The quality,
reliability and turn-around time of our best-in-class FISH testing
enabled us to win this important business. It has also allowed us to
gain business from a number of sizeable customers who were not happy
with the quality and reliability of FISH test offerings of certain
larger competitors. For example, we won the business of one large
statewide health care provider after we succeeded in providing correct
diagnoses on a number of samples that a large competitor was unable to
achieve. In addition, we also took a large state university hospital’s
HEME FISH business from another competitor based on our FISH tests’ high
quality, reliability and timeliness,” stated Kenneth A. Berlin,
President and Chief Executive Officer of Rosetta Genomics.

The FISH service offered by RosettaGX is best-in-class, with a highly
competitive success rate in obtaining informative results in 98% of
cases, and a turnaround time of 3 to 4 days. Rosetta’s FISH technology
is used for the early detection of genomic changes, which may detect
cancer, measure the potential aggressiveness of the disease, and
identify if patients are likely to respond to specific targeted therapies
